为什么 rbenv 在 Mac OS Catalina 上不起作用 [英] Why rbenv does not work on Mac OS Catalina

问题描述

我正在尝试运行一个版本为 2.4.1 的 Ruby on Rails 项目，我的系统是 2.6.x.我所做的是通过 Rbenv 安装旧版本的 Ruby 然后我执行了以下命令:

I'm trying to run a Ruby on Rails project which has the version 2.4.1and my system is 2.6.x. What I did was install via Rbenv the old version of Ruby then I did the following commands:

rbenv global 2.4.1 -> to change global Ruby version

ruby -v 
ruby 2.6.5p114

rbenv global
2.4.1

所以有一些问题，因为我想使用 2.4.1 但似乎不起作用.我无法启动捆绑包，因为它说我没有安装 2.4.1.

So there is something wrong as I would like to use 2.4.1 but seems not working that. I'm unable to start the bundle as it is saying I don't have 2.4.1 installed.

我需要一个 Mac OS Catalina 的解决方案，正如我在网上找到的那样，但没有任何效果并且无法启动项目.

I need a solution to Mac OS Catalina as I did as I found online but nothing works and cannot be started the project.

推荐答案

尝试 eval "$(rbenv init -)".如果这解决了您的问题，请将该行添加到您的 .bash_profile 或 ~/.zshrc(感谢@Agney，请参阅下面的评论)

Try eval "$(rbenv init -)". If that solves your problem, add that line to your .bash_profile or ~/.zshrc (Credits to @Agney, see comment below)
